-Broadcom Kona Family timer
------------------------------------------------------
-This timer is used in the following Broadcom SoCs:
- BCM11130, BCM11140, BCM11351, BCM28145, BCM28155
-
-Required properties:
-- compatible : "brcm,kona-timer"
-- DEPRECATED: compatible : "bcm,kona-timer"
-- reg : Register range for the timer
-- interrupts : interrupt for the timer
-- clocks: phandle + clock specifier pair of the external clock
-- clock-frequency: frequency that the clock operates
-
-Only one of clocks or clock-frequency should be specified.
-
-Refer to clocks/clock-bindings.txt for generic clock consumer properties.
-
-Example:
-	timer@35006000 {
-		compatible = "brcm,kona-timer";
-		reg = <0x35006000 0x1000>;
-		interrupts = <0x0 7 0x4>;
-		clocks = <&hub_timer_clk>;
-	};
